not much to say but you can ramp. fun to mess around with at fields and scare newbs. Installs in like 5 min. all you do is pull out stock chip and stick the new chip in. Its fun to shoot 24 bps when you are only pulling the trigger at 9 bps.

Conclusion:

If you want to shoot hella fast but you dont do tourneys, get this. i give a 9 cus its not tourney legal.
